. This invention relates to an adjustable supporting means comprising a hanger and clip suitable for installing furring strips or the like on ceilin and walls and other supporting surfaces, %to support T bar furring strips and like construction materials).

The objects of this invention are to provide a hanger which may be used with any type v of supporting surface, to provide an adjusting means which allows theclip to be easily spacedat any distance from the supporting surface after the hanger is installed, and to provide a clip which firmly grips a plate or T bar furrlng strip. Other ob ects will bei come apparent from the following specificat1on and attached drawings in which:

Fig. 1'is a broken sectional view illustrating a typical installation of a hanger and clip embodying the resent improvements; Fig. 2 is a sectiona view showing a method of fastening a T bar in the clip; I Fi 3 is a detached perspective view of one orm of the hanger and clip;

Figs. 4 and 5 illustrate modifications of certaln details of the invention;-

Fig. 6 is a perspective view illustrating a method of using the clip on a corner installation;and Fig. 7 is a perspective view of a strap shown in Fig. 6.

The su portin means shown in the draw-- in sis .a apted or use in conjunction with ar furring stripsl which form the sub ject matter of the co-pending application of Ralph F. Norris, Serial No. 249,453, filed January 25, 1928, although it is not limited, necessarily, for use with this specific type of furring strip. Such furring strips are em- 2- which'face sound-absorbing material 3, as described in Norris Patent No. 1,726,500 issued August 27, 1929. The sound-absorbing material 3 and the perforated metal facing membrane or pans 2 are usually mounted over a wall, or ceiling surface or over the supports for a wall or ceiling surface. The per orated metal pans 2 thus constitute the exposed surface 0 the room and it is therefore necessary that the pans be accurately aligned to insure a flat appearance to the ployed for supporting perforated metal pans stiffen the cli eye. The support, which may be a plastered, wooden, concrete or other surface, or may .be spaced wood, steel or concrete beams, or other construction, usually presents an irre ular surface. Tile-like units employed 1n building a new surface over said support must be levelled or aligned properly to present a regular appearance to the eye, and the construction described and claimed in this application provides a device for doing this quickly and easily. Furthermore, it provides a device which is simple and can be installed readily.

In the accompanying drawings 4 represents any ceiling, wall, or other supporting surface which it is desired to face with sound-absorbin'g material 3 which, in turn, isfaced with perforated metal membrane or pans 2 which are supported by 1. The means for su porting the .furring strips, according to tl 'ie present invention, comprise hanger and clip parts which are shown, detached in Fig. 3 and installed in T bar furring strips,

Fig. 1. The hanger comprises a bolt 5 varying in length according to the requirements of the job. If the bolt is tobe anchored in a plastered ceiling-or other relatively thin supporting surface 4, a toggle 6 is used as an anchor in the ordinary manner as shown.

If the bolt is-to be'anchored in concrete a threaded expansion device 7 of conventional form maybe used. In the preferred form, an adjusting plate 8 is threaded onto bolt 5 and screwed up against the surface 4 as shown I v in Fig. 2. This plate may be made of sheet metal. Between the adjusting plate 8 and the head of bolt 5 is having a washer 10 between.

The clip may be of the form shown in Figs, 2 and 3. It comprises a channel shaped section of sheet metal, the web section of which is recessed as at 9 by depressing the metal transversely. and outwardly as shown, to and to provide space for the bolt head an washer. The depressed portion 9* contains the hole 5 for the bolt 5.

.This hole is preferably in the form of a slot to permit lateral adjustment of the clip.- The legs 11 of the clip have flanges 12 or other means formed at their ends for the purthe clip 9 preferably pose to be hereinafter explained. By screwing the bolt 5 up or down in the toggle 6 the clip 9 can be positioned in alignment with the other clips mounted in the supporting surface. During this operation, plate 8 maintains bolt 5 firmly in position against the pressure of the screw driver or other tool used in adjusting the bolt. When a hanger is mounted and adjusted on a supporting surface as just explained, the furring strip 1 is placed in clip 9 as shown in Fig. 2. A suitable tongs 13 is then engaged with legs 11 of the clip above'the flanges 12 and the tongs closed. The legs 11 are thereby bent inwardly as shown in Fig. 1, the flanges 12 exerting a pulling action whereby the clip grips the base of the T bar 1 tightly. The perforated metal pans 2 are thereafter attached to the furring strips as described in the applications above mentioned.

In the modification shown in Fig. 4, a spring steel adjusting device 14 is used in lieu of the adjusting plate 8. The spring steel legs of the device 14 keep a steady pressure on clip 9 and thereby allow the bolt 5 to be screwed to any position. When anchor 7 is used the adjusting plate 8 or spring 14 may be omitted entirely.

Where the T bar 1 is to be mounted on a corner post or other angular formation 15 a steel strip 16, shown in Figs. 6 and 7 is used to advantage. This strip which may be made of thin soft steel, can be bolted through holes 17 to the column at the proper point so as to line up clip 9 with other similar clips. The soft steel readily accommodates itself to any position. The clip 9 is then secured to the strip 16 as by bolt 18, the T bar 1 being thereafter fastened to the clip in the above described manner. The end flanges 2 of the pans may be cut away and the sound-absorbing material therein removed at the corners to accommodate the T bar, as shown in Fig. 6. The holes 17 and 19, the latter of which receives the bolt 18, may be slots to allow lateral adjustments to be more easily made.

Although I have shown and described certain features of my improvements for the purpose of illustration, I do not wish to be restricted specifically thereto except as so limited by the appended claims.

What I claim is: 1. In combination with a supporting surface and a T bar, a hanger comprising a bolt and a cooperating threaded anchor carried by the backing of said surface, an adjusting plate in threaded engagement with said bolt and in contact with said supporting surface, a recessed and slotted sheet metal clip carried by the head of said bolt and spaced from said surface, said bolt head being disposed within said recess and a washer in said recess and interposed between said clip and bolt head, said clip straddling the base of said T bar and being turned inwardly over the edges of said base to firmly grip said T bar.

2. In combination with a supporting surface and a T bar, a hanger comprising a bolt and a cooperating anchor carried by the backing of said surface, an adjusting plate in threaded engagement with said bolt and in contact with said supporting surface, and a sheet metal clip carried by the head ofsaid bolt and spaced from said surface, said clip straddling the base of said T bar and being turned inwardly over the edges of said base to firmly grip said T bar.

3." In combination with a supporting surface, a hanger comprising a bolt and an anchor carried by the backing of said surface, a sheet metal adjusting plate in threaded engagement with said bolt and in contact with said supporting surface and a channel-shaped sheet metal clip carried by-the head of said bolt and spaced from said surface, the legs of said clip being directed away from said surface, said clip having an elongated opening through which said bolt passes.

4. In combination with a supporting surface, a hanger comprising a bolt and a threaded anchor, said anchor being carried by the backing ofsaid surface, an adjusting plate in threaded engagement with said bolt and in contact with said supporting surface, and a channel shaped clip carried by the head of said bolt and spaced from said surface.

5. In combination with a supporting surface, a hanger comprising a bolt and an anchor, said anchor being carried by the backing of said surface, a channel shaped clip carried by the head of said bolt and spaced from said surface, and means between said clip and said surface cooperating with said anchor to space said clip from said surface.

6. A clip comprising a sheet metal channel section, means formed on the ends of the legs of said channel section to allow a pair of tongs to firmly pull and pinch said legs onto a bar to be gripped by said clip, the web of said channel section being recessed outwardly and having an opening therethrough.

7. A device for supporting a member in spaced relation with respect to a supporting structure comprising a bolt threadedly carried by said structure whereby the bolt head can be adjusted toward or away from the adjacent surface of the structure, and a clip supported by the head of said bolt, said clip having a portion depressed outwardly thereof to provide an inner recess for the head of the bolt, and having legs bendable into engagement with the member to be supported.

8. Means for adj ustably supporting a member in spaced relation with respect to a supporting structure comprising a bolt adapted to be th'readedly attached to said structure whereby the head of said bolt can be moved toward or away from said structure, and a said bolt, said clip having a ortion of .the web depressed outwardly to orm an inner recess for receiving the head of said bolt, said depressed portion having an opening throu h which the bolt extends, the legs of said chp hein bendable into engagement with the mem er to be sugported.

In testimony w ereof, I have subscribed my name.
